What might happen to an astronaut if she spent a long time on a plante wit less gravity?

If you were to spend a month in bed, your muscles would "atrophy" or weaken through lack of use. It would take time to regain your strength by exercising.
Astronauts in space, or living for long periods on the Moon, Mars or Ganymede where gravity is lower, would weaken unless they exercised to keep their muscle tone. If you spend a year floating in zero-G for a year, you wouldn't be able to walk at all.
Science Fiction writers have speculated that humans born in space or on the Moon might never be able to come to Earth, because they would be unused to living in Earth-gravity. On the other hand, humans raised on high-gravity planets might develop very strong muscles just from having to stand up and walk, and might be champion weightlifters or athletes on Earth.

What might happen to the blood of an astronaut subjected to extremely low pressures?
it would boil due to the vapor pressure properties of blood
What is the colour of the earth's atmosphere?
The color depends on where, when, how and with what you are looking at the atmosphere. For example, astronaut might see it as "clear" but people watching a sunset might see it as more orange/red.
Could the earth ever loose its gravity?
No. The only way the gravity can dissapear is if the earth dissapears. Unless they make a new bomb, which might be possible that would change the atmospheric level than it might.
How might the experience of the Apollo 17 astronauts been different from the Apollo 11 astronauts?
The difference of the apollo 11 astronauts wand the Apollo 17 astronaut was that in Apollo 17 astronaut Harrison Schmitt was a scientist, while All in the Apollo 11 were astronauts.
How often do astronauts fly into space?
Astronauts currently work in six month shifts on the international space station. A single astronaut might fly only once in his career. Others, however, have flown as many as five or six times! (Astronaut training is expensive.)

What would happen if their is no gravity?
If there was no gravity your eyes might have the chance of your being pulled out of your head if not the proper gear is with you also would be lifted from the ground because you will not have the gravity to hold you down
What is the difference between the astronaut's mass on the earth and on the moon?
There is no difference in an astronaut's mass no matter where he or she might be. Mass is a constant, as opposed to weight which is dependent upon acceleration.None.Put simply. Mass is a measurement of how much matter is in an object, whereas weight is a measurement of how hard gravity is pulling on that object. As their is less gravity on the moon, your weight would be different, your mass would not.
What might happen if an astronaut floating in space moved the north poles of two magnets together and let them go?
The result would be the same as on Earth (except in 3D). Something different would happen (i) if the astronaut let go of one magnet before the other or (ii) if there were two astronauts, with one magnet each. (In space, the astronaut could spin, as well (except much more slowly).)
Where might an astronaut look for water on Mars?
At the poles of Mars.
How many hours does an astronaut work in a week?
An average astronaut works 9 hours a day. In a week an astronaut works 63 hours. It also depends if you are more experienced or a beginner as an astronaut. If you are experienced you work that amount. But if you are a beginner than you might work less.
What would happen to the orbits of the planets if the amount of gravity produced by the sun reduced to almost 0?
The orbits of the planets would all be much larger if the sun had less gravity. They might even just fly off free.
What might an astronaut eat during a typical lunch or dinner?
Launch meat
Does an astronaut costume come with a helmet or a ship?
A ship might be a little much to ask for an astronaut costume. A helmet might be included, but it would have to be a high quality costume that costs a pretty penny and might not get a lot of use. You could also buy a replica costume.
What is the fear of gravy called?
An irrational fear of gravity is called barophobia. Someone who has this phobia usually fear that they might be crushed by gravity, gravity might cease to exist or that gravity will cause them to fall.
Do all of the moons not have gravity?
Everything has gravity, the bigger it is the more it has. Moons DO have gravity, but it might be less than Earth's.
What might be a gravity wave?
there are no gravity waves gravity and light are what you could call thinned out parts of matter,and matter and gravity are connected and part of one big thing made of maybe boson material.this might seem crank but it is true.
